Penelitian ini bertujuan untuk mengetahui pengaruh jarak tanam dan jumlah bibit perlubang tanam terhadap pertumbuhan tanaman sorgum (Sorghum bicolor L.) pada lahan pesisir. Sorgum merupakan tanaman serealia yang memiliki toleransi tinggi terhadap kondisi lingkungan ekstrem seperti kekeringan dan tanah marginal, sehingga cocok dibudidayakan di wilayah pesisir. Penelitian dilaksanakan pada bulan Maret - September 2023 di lahan percobaan Fakultas Pertanian Universitas Borneo Tarakan, menggunakan Rancangan Acak Kelompok (RAK) dengan dua faktor, yaitu jarak tanam (40×20 cm, 50×20 cm, 60×20 cm, dan 70x20 cm) dan jumlah bibit perlubang tanam (1, 2, dan 3 bibit), masing-masing diulang tiga kali. Parameter pengamatan meliputi tinggi tanaman, jumlah daun, panjang daun. dan lebar daun pada umur 1, 2, dan 3 MST (minggu setelah tanam). Data dianalisis menggunakan ANOVA dan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf 5%. Hasil penelitian menunjukkan bahwa baik perlakuan tunggal maupun kombinasi jarak tanam dan jumlah bibit tidak memberikan pengaruh yang nyata terhadap seluruh parameter pertumbuhan yang diamati. Namun secara deskriptif, perlakuan dua bibit perlubang tanam (B2) dan jarak tanam 40 cm x 20 cm (J1) serta 60 cm x 20 cm (J3) cenderung menghasilkan nilai pertumbuhan lebih tinggi dibandingkan perlakuan lainnya. Dengan demikian, meskipun tidak signifikan secara statistik, penggunaan dua bibit per lubang tanam dan jarak tanam 40 cm x 20 cm serta jarak tanam 60 cm x 20 cm berpotensi memberikan pertumbuhan tanaman sorgum yang lebih baik pada lahan pesisir. This study aims to determine the effect of plant spacing and the number of seeds per planting hole on the growth of sorghum plants (Sorghum bicolor L.) on coastal land. Sorghum is a cereal crop that has high tolerance to extreme environmental conditions such as drought and marginal soils, making it suitable for cultivation in coastal areas. The research was conducted in March-September 2023 on the experimental land of the Faculty of Agriculture, University of Borneo Tarakan, using a Randomized Group Design (RGD) with two factors, namely planting spacing ( 40 * 20 cm, 50×20 cm, 60 * 20 cm, and 70 * 20 cm) and the number of seeds per planting hole (1, 2, and 3 seeds), each repeated three times. Observation parameters included plant height, number of leaves, leaf length, and leaf width at 1, 2, and 3 weeks after planting. Data were analyzed using ANOVA and continued with Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that neither the single treatment nor the combination of planting space and number of seeds had a significant effect on all observed growth parameters. However, descriptively, the treatment of two seeds per planting hole (B2) and plant spacing of 40cm * 20 cm (J1) and 60cm * 20 cm (J3) tended to produce higher growth values than other treatments. Thus, although it was not statistically significant, the use of two seeds per planting hole and a planting space of 40cm * 20 cm and a planting space of 60cm * 20 cm had the potential to provide better growth of sorghum plants on coastal land.

THE EFFECT OF KARAMUNTING (Melastoma malabatrhicum) LEAF EXTRACT ON BREEDES TOWARD THE NUMBER OF BREEDING AND LIFE SURVIVAL OF BETTA FISH (Betta sp) Abstract Betta fish (Betta sp) is a freshwater ornamental fish that is excellent because of its high economic value, thus encouraging cultivators to cultivate it. To produce the mature Betta fish, efforts are needed to accelerate and improve the reproductive performance of Betta fish. This study aimed to examine the effect of giving karamunting leat ectract (Melastoma malabatrhicum) to brooder on the number of tillers and survival Betta fish. This study used completely randomized design (CRD) which consisted of four treatment three replications. The use of karamunting leaf ectract in this study was treatment A: (Control), treatment B was injections of ectract dose ( 1 g/g BW), treatment C was injection of ectract dose (5 g/g BW) and treatment D was injections of ectract dose (10 g/g BW) the parameters observed include; egg diameters percentage of chicks, sr, water quality measuremeants, the results showed that the use of ectract at a dose of 1 g/g. 5 g/g, 10 g/g indicated a larger egg diameter than te control. The highest number of tillers was obtained in treatment B (10 g/g BW) with a total of 37.28% the survival rate of Betta fish from treatment A, B and C had value above 95%. While treatment D there was a total death on the third day. Giving karamunting leaf ectract gave a higher value on the size of the egg diameter. the percentage of the number of tillers. And the SR value Betta fish seeds. Keywords : ectract, Karamuntinng, seeds, Betta, egg

Ikan lele merupakan salah satu komoditas yang sangat diminati masyarakat dan ikan lele juga memiliki permintaan pasar yang cukup tinggi. Upaya dalam peningkatan produksi ikan lele melalui subsektor perikanan budidaya dapat dicapai dengan adanya penyediaan benih yang cukup tahan dan berkualitas. Penelitian ini bertujuan untuk mengetahui pengaruh dari uji tantang pada benih ikan lele tanpa pemberian pakan Pasca Pemijahan Dengan Induk Yang Diberi Tepung Kunyit (Curcuma domestika) Dan Hormon Tiroksin. Uji tantang yang dilakukan pada penelitian ini menggunakan benih ikan lele berumur 3 hari. Penelitian terbagi menjadi dua tahapan, tahapan pertama yaitu pemberian dosis (4,8 gram tepung kuyit, 0,1 mg horomon tiroksin). tahapan kedua yaitu pengujian dosis. Uji tantang pada benih ikan lele dilakukan selama 12 hari. Parameter yang diukur selama penelitian yaitu kelangsungan hidup, dan pertumbuhan benih ikan lele, serta parameter kualitas air (pH, suhu, DO, dan amoniak). Hasil penelitian menunjukkan kelangsungan hidup benih ikan lele pada pemijahan induk yang diberi tepung kunyit (4,8 gram) sebesar 42% dan hormon tiroksin (0,1 mg) sebesar 45%, sedangkan perlakuan pada kontrol sebesar 45%. Hasil pertumbuhan pada benih ikan lele menunjukkan hasil yang tidak berbeda jauh antar perlakuan. Sedangkan, hasil pengukuran kualitas air selama penelitian didapatkan hasil pengukuran yang masih tergolong baik bagi benih ikan lele (Clarias gariepinus) Catfish is a commodity highly preferred by many people and demanded by the markets. The efforts made to increase the catfish production through aquaculture sub-sector can be achieved when the quality and resistant seeds are adequately provided. This research aimed to figure out the effect of non-feeding challenge test on catfish seeds after spawned from broodstock administered with turmeric powder (Curcuma domestica) and thyroxine hormone. The challenge test was conducted in this research using 3-day old catfish seeds. The research was divided into two stages: dosage administration (4.8 grams of turmeric powder and 0.1 mg of thyroxine hormone), dosage testing. Challenge test on catfish feeds was performed in 12 days. The measured parameters included the catfish seeds’ survival and growth, as well as water quality level (pH, temperature, DO, and ammonia). The research results showed that cthe carfish seeds’ survival level spawned from their broodstocks administered with turmeric powder (4.8 grams) was 42% and those with thyroxine hormone (0.1 mg) wa 45%, while the control treatment was 45%. The research results also shot that the growth of catfish seeds had no significant different with that in the other treatments. In addition, the research results indicate that the water quality was still relatively good for the catfish seeds (Clarias gariepinus).
